應用領域: 紙漿及造紙 -- 黑液,綠液,紅液,白液,液漿,塗料,PVA,樹脂,塔羅油食品工業 -- 蔗糖,果糖,葡萄糖,果醬,凝膠劑,牛奶,水果汁,
軟飲料,啤酒,番茄醬化學工業 -- 硫酸,鹽酸,磷酸,氫氧化鈉,碳酸鈉,尿素,發煙硫酸,表面活性劑,乙二醇

工作原理: 從LED(見圖)發射出來的發散光束從棱鏡上表面進入棱鏡,不同角度的光以不同角度在棱鏡內的各面或反射或穿透而過。棱鏡外有所測溶液，當光線的入射角大於臨界角,光線穿過介面射入溶液。而小于臨界角的入射光線則反射回來,之後,光束射向棱鏡上方一單線CCD。折射儀的CCD有2000個以上光敏象素。系統反復掃描,取得CCD 上的明暗圖像。掃描所得信號,其明暗區域之比,隨所測溶液的濃度不同,折射臨界角不同而變化。經系統微處理機計算,得出所要的測量值，其可以是折射率,Brix,濃度或其它度量單位。

MPR E-Scan Refractometer

The MPR E-Scan is a rugged, industrialized, in-line process refractometer. It directly measures the refractive index of process fluids and then displays the reading in any number of customer-desired units (Brix, Percent Solids, Dissolved Solids, SGU, R.I., etc.). This reading may be used as an error indicator or part of a complete process control system. A high-resolution color display and a 4-20mA output is standard. HART® protocol, RS-232, and RS-422 outputs are available.

Each sensing head is custom tailored and calibrated specifically for the desired process application to ensure the most accurate and useful reading. A simple 0-10Vdc signal is used to transmit the reading from the sensing head to the electronics console, ensuring a robust reading that has a minimal chance of being effected by interference. The entire package is NEMA 4X rated and designed and manufactured with the best materials for each application to provide years of trouble-free service with a minimum amount of maintenance.

Applications

Paper Industry - The MPR E-Scan has numerous applications in the paper industry. The most common applications are on black liquor and green liquor. More information on these can be found by clicking the links below. Other applications include red liquor, white liquor, tall oil, and resin. Please contact us for more information.
- Green Liquor
- Black Liquor
Chemical Industry - The MPR E-Scan has numerous applications within the chemical industry. Some of the most common are listed below. In general, the MPR E-Scan can measure the strength of a chemical when diluted with water (or another chemical). If there is a concern with optical coating, a hand-operated brush cleaner is normally the preferred method. Various material alloys are available for wetted parts and Teflon® coating is available for non-wetted parts. Our extensive experience with in-line process refractometers has resulted in numerous other successful applications. Contact us today to discuss your application.
- Sulphuric Acid
- Hydrochloric Acid
Food Industry - The Electron Machine Corporation developed the first in-line process refractometer more than 50 years ago when orange juice was first concentrated. Since that time, our refractometers have been successfully applied on many more applications. Our latest in-line process refractometer, the MPR E-Scan, has many features that make it very well suited to all types of industrial food processes.
